BROODER.

Application led April 28, 1922.

To all 107mm. t may concer/n.

Be it known that l. liliana* iieiisim, citizen of the United Irtates, residing` at Forman, in the county-.fv of Sargent and State of orth Dakota, have invented certain new and useful Improvements in Broeders, of which the following is a specification, reference being had to the accompanyingdrawings.

This invention relates to improvements in brooders, and an important object of the invention is to provide a device of this character which is extremely simple in consti-uction and operation and which may be very readily cleaned.

A further object of the invention iste provide a brooder of the outdoor type having means for protecting` the lamp, by means of which the brooder heated, from gusts of wind and' the like, supplying to the lamp at alltimes a steady current of fresh air to insure proper operation thereof.

These and vother objects l accomplish by the construction and arrangement shown in the accompanying drawings wherein for the. purpose of illustration is shown a preferred embodiment of my invention and wherein like reference characters designate like parts throughout.

In the drawings:

Figure 1 is a perspective view showing a brooder constructed in accordance with my invention Figure 2 is a transverse vertical sectional view taken therethrough; and

Figure 3 is a section on the line 3 3 oi' Figure 2.

Referring now more particularly to the drawings, the numeral 10 indicates a tangular framework having an open top and bottom. This framework is provided on the inner faces of the under sides thereof with notched brackets 11 adapted for the reception of the lower end of a plate 12. Be* tween the brackets and one end of the frame 10 the upper surface of the frame is covered by a plate 13 which is removable and provided upon the lower surface thereof with` batons 14 preventing movement of the plate 13 with relation to the frame, the ends of the batons abutting against the brackets and against the end walls 10b Of the frame 10 and the outer side faces thereof abutting against the side walls 10a. This plate is provided with perforations 15 for a purpose presently to appear.

Serial No. 556,666.

The numeral 16 indicates a broeder proper confiprising` walls 17, a top 18 and a bottom 19. The walls 17 are provided adjacent their upper ends with fresh air inlet openings 20 for 'the purpose of admitting;` fresh air to the closed chamber, and one of these walls has formed therein a door` 2l closed by a slide The side wall has secured thereto opposite the opening so as to cover theopening when the slide is removed, strips of woolen cloth or the like, as indicated 23, to prevent the entrance of draft and the loss of heat through the doorway.

The top 18 is preferably formed in hingedly connected sections 1S and 18h. the section 13a being permanently secured to the walls 17. The bottom 19 is provided een` trally with an aperture 24': of desired size which is covered, and to the under surface of the bottom 19 is applied a plate 25 extending; considerably beyond the edges of the opening and secured to the bottom. The recess thus formed in the bottom is filled with clean fine sand or soft dirt as desired.

Secured to the outer surface of the side walls 17 is a depending skirt 26 forming a support for supporting' the brooder in spaced relation to the ground. @ne side of the skir 26 consists of separate sections having): their adjacent ends spaced a distance equal to the width of the plate 12 which normally closes tue opening thus formed.

ln the use of my device a trench or pit is du in the ground in which the frame 10 is disposed and the lamp seated upon the ground within the frame at the end thereof remote from that covered by the grating 13. The broodei1 is then placed over this end so that the plate 12 closes the opening between the skirt sections and when in this position the lamp 28 is disposed beneath the plate 25 to impart its heat thereto for transmission to the dirt or sand disposed in the opening, 24. The air to supply the lamp passes through the openings 15 of the plate and between the walls of the frame to the lamp and the gases from the lamp after circulating against the lower surface of the bottom 19 of the brooder pass outwardly at these openings, the lamp heating,` the earth within the chamber and at the same 'time preventing crowding` of the chicks about the heated dirt or sand. Attention is directed to the factthat the lamp is so disposed as not to be subject to sudden drafts o r puffs'of wind and is at the same time provided with an anip'le aniount of air for proper operation. It will furthermore be obvious that the grating 13 will prevent the entrance of rodents beneath the broodei` and will also serve to prevent small chicks from falling into the pit in which the frame 10 rests.

From the foregoing it is believed to be obvious that a brooder constructed in accordance with my invention is particularly well adapted for the purpose for which. it is intended for the reason that the construction thereof is extremely simple and permits of the use of papers upon the bottom of the broodeito prevent dirtyingl thereof by the chicks and for the reason that the lamp is materially protected against gusts of wind. It will furthermore be obvious that the construction as hereinbefore set forth is capable of some change and modification without materially departinlg` from the spirit of my invention and I accordingly do not limit myself thereto except as here? inafter claimed.

I claim:

l. l'n al brooder, a frame adapted for arrangement within a pit land having one end thereof covered by a grating, a plate eX- tending; upwardly from the frame at one end of the grating, a lamp disposed within the frame and restinpupon the bottom of the pit in which the frame is disposed, and a brooder chamber provided with a depending skirt having" an aperture therein permittingremoval of saidlamp,`said aperture beingnormally closed said plate.

2; In a broo'der; a frame adapted for arrangement within a pit and having one end thereof covered by a grating, a plate extendingi upwardly from the frame at one end of the grating, a lamp disposed within the frame and resting1 upoii the bottom of the pit in which the frame is disposed, a brooder chamber provided with a depending skirt having an aperture therein permitting removal of said lamp, said aperture being normally Closed by said plate. an aperture formed in the bottom of the brooder chamber above the lamp, a plate of `greater size than said opening secured to the underside of the bottom of the brooder chamber and covering' saidV openino, and a filling of earthy material disposed within the opening.

3. ln a brooder, a framework adapted to be disposed within a pit, brackets secured to the adjacent faces of the sides of said franjework, a platehaving its lower end mounted in said brackets and extending upwardly from the framework, a grating covering the end of the framework at one sidel of the plate, a brooder chamber having a depending' skirt provided with an aperture arranged above the opposite end of the frame work, a lamp. disposed within the framework at the last named end thereof,`said skirt havingan aperture therein aifording access to said lamp and normally closed by said plate', said plate being removable from said brackets, and said grating` being removable from said frame.

In testimony whereof Ihereunto affix my signature. v
